Remember, in order for the Jukebox Multimedia to be able to play the video, it must have an MP3 (MPEG layer 3) stereo sound track. If the source video file did not have an MP3 stereo sound track then your destination file will have no sound. Mpeg4 translator will signal this error condition. Obviously, it is pretty useless to have the video file without sound. What you will need in this case is an MP3 encoder available for Virtual Dub to use. There are MP3 encoders (usually packaged together as an encoder and decoder) available on the Web. If you choose to use the LAME codec, make sure that you have a version built with the ACM
If you are unsure what codecs (audio and/or video) your computer has, you can see the list, as shown to the left, by going to the following location. Click on Start > Control Panel > Multimedia > Devices and then you will see a list which includes the Video Codecs and the Audio Codecs which are installed in your system. Decoding of MPEG 2 video files is currently not supported by Mpeg4 Translator. These are usually .mpg or
.mpeg format files, not the required AVI file. There are other tools found on the Internet that may be downloaded in order to help you with these file types. A good starting place is the web site www.digital- digest.com.
